A Preliminary Analysis of the Application and Testing of Future Integrated Sensing-and-Communication Technology
2024-07-17
Currently, smart vehicles, smart homes, and the low‑altitude economy are all posing new demands on integrated sensing‑and‑communication technologies. By fully leveraging the time, spatial, and other multidimensional resources shared between wireless communication and radar sensing, it is possible to achieve coexistence, mutual support, and mutual benefit between these two technologies.
To achieve a more reliable physical connection, integrated sensing-and-communication technology requires On-demand cooperative sensing across multiple frequency bands, including sub-6 GHz, millimeter wave, visible light, and terahertz. To meet the sensing and communication requirements of various applications.
2024 marks the inaugural year of 5G‑A commercial deployment, and as one of its key new capabilities and innovative directions, integrated communication–sensing has attracted significant attention. Integrated communication–sensing refers to the seamless convergence of communication and sensing systems, enabling efficient, intelligent exchange of multidimensional sensing data across multiple distributed sensing servers and endowing networks with enhanced perceptual capabilities.
Integrated communication–sensing, due to Characteristics such as multisensory experience, interactivity, and intelligence It has a wide range of application scenarios in areas such as intelligent manufacturing and industry, the low-altitude economy, smart transportation, smart homes, human–machine interaction, and environmental monitoring.
Smart home
The integrated communication–sensing system can Utilizing wireless signals transmitted by base stations or Wi‑Fi routers to achieve fine-grained perception of human movements and behaviors. , enabling human–machine interaction—for example, users can switch between controlling furniture and appliances by adopting different gestures; in hazardous areas such as balconies and windows, it can issue alerts to monitor and prevent objects from being thrown from height.
Smart Transportation
The synesthetic integrated system can Leveraging the high altitude and wide coverage of cellular base stations, it enables high-speed vehicle-to-vehicle communication and surrounding environment perception, supporting intelligent traffic management.
Low-altitude economy
Deploy on a drone Integrated communication–sensing systems can enhance the mutual coordination and collaborative sensing capabilities between communication and sensing functions. For computationally intensive tasks such as high-precision perception and tracking, the UAV can aggregate its local processing results at the ground base station, which then performs aggregated processing of the perceptual information, enabling it to accomplish… Police and security, disaster Difficult on-site rescue, battlefield information monitoring, logistics and transportation, traffic management, and agricultural and forestry protection, among others.
In the face of the continuous advancement of the aforementioned future integrated sensing‑and‑communication technologies, phased‑array radar in wireless signal sensing, as well as… Wireless communication networks all impose stringent quality requirements, necessitating more reliable, stable, and efficient testing solutions to meet these demands.
Among these, programmable attenuators are widely used in testing and in simulating signal attenuation under real-world conditions, making them particularly important for validating the performance of wireless communication systems.
